HERMANN HEUSS AND GEORGE C. F. VATER,OF DAYTON, OHIO, ASSIGNORS TO THEC. W. RAYMOND COMPANY, OF DAYTON, OHIO.

DRIER FOR CLAYWARE.

To all whom it may concern.

Be it known that we, HERMANN HEUss, a citizen of the Republic ofSwitzerland, and GEORGE C. F. VATER, a subject of the Emperor ofGermany, residing at Dayton, in the county of Montgomery and State ofOhio, have invented certain new and useful Improvements in Driers forClayware; and we do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in driers foreliminating the excessive moisture from clay ware preparatory toburning.

The object of the invention is to provide a drier of the above type inwhich liquid fuel, such as oil or gas which contains no constituentsinjurious to the clay, may be used, and which will allow the products ofcombustion to come in direct contact with the ware.

Another object of the invention is to provide a drier in which the heatradiating from the direct or primary fired tunnel is utilized in anothertunnel.

Referring to the annexed drawings, Figure 1 is a longitudinal, vertical,sectional elevation of the drier on the line a a of Fig. 2, withintermediate portions broken away; Fig. 2 is an elevation of the furnaceend of the drier; Fig. 3 is a section on the line b b of Fig. 2, a c ofFig. 4:, and cl d of Fig. 7; Fig. 4 is a section on the line 6 e of Fig.1 and f f of Fig. 3; Fig. 5 is a section on the line 9 g of Fig. 1 and hh of Fig. 3; Fig. 6 is a section on the line 2' i of Fig. 1; and Fig. 7is a section on the line j j of Fig. 1.

Throughout the specification and drawings similar reference charactersindicate corresponding parts.

Referring more particularly to the drawings, 1 represents the sides, 2the top and 3 the bottom of a drier tunnel which receives the clay wareto be dried. WVhile in the drawings a plurality of tunnels thusconstructed are illustrated, it will be understood that all of thetunnels and coacting devices are of identical construction; consequentlyonly one will be described.

above the bottom of the tunnel on cross rails 4, is a track 5 on whichtrucks (not shown) supporting the clay ware to be dried are run. Theends of the tunnels are provided with doors 6 which are closed when theware therein is being dried. One end of the tunnel communicates with afurnace constructed as follows.

Mounted below the end of the tunnel, opposite the stack, is a furnace 8provided with an opening 9 adapted to receive a burner 10 for either oilor gas. The furnace 8 is also provided with an opening 11 in the bottomthereof which allows suflicient air to enter the furnace to supportcombustion therein. The furnace 8 may be provided with checker work 12which is instrumental in maintaining sufficient heat within the saidfurnace to secure proper combustion of the oil or gas. Above the rearend of the furnace 8 is a mixing chamber 13 which communicates with thefurnace through ports 14, and with the tunnel through ports 15. Theproducts of combustion from the furnace pass through the ports 14,chamber 13 and ports 15 to the interior of the tunnel where they come incontact with the ware to expel the excessive moisture therein. However,as the temperature of the products of combustion leaving the furnace isat a point which would cause injury to the ware, suflicient air is mixedwith the said products of combustion as they pass through the mixingchamber, to lower their temperature to operative limits. The air forthis purpose may enter the mixing chamber 13 through ports 17 in theside thereof, which ports communicate with pas sageways 18 along thesides of the furnace. The forward ends of the passageways 18 areprovided'with openings 19 which receive air from the out-sideatmosphere. The tunnel may also be provided with openings 21 at thefurnace end above the furnace, which admit air to the tunnel withoutbeing previously mixed with the products of combustion, but which isheated by radiation from the furnace below. This air may be used tofurther reduce the temperature of the products of combustion.

It will be seen that in a drier thus constructed, the high temperatureof the products of combustion, which is necessary to secure completecombustion, is reduced to a point which will not injure the ware, bymixing the same with a suitable amount of of the tunnel. To utilize thisheat, an upper tunnel is mounted above the lower tunnel. The uppertunnel consists of side walls 22 which are a continuation of the walls 1of the lower tunnel, and of a top 23. This upper tunnel is also providedwith doors 6, and a stack 24 which creates a circulation. The top 2 ofthe bottom tunnel forms the floor of the upper tunnel, and as said top 2can be made comparatively thin, suflicient heat will be radiated to drylight or hollowclay ware within the upper tunnel.

Having described our invention, we claim:

1. In a drier, a drying tunnel, a stack communicating with one endthereof, a furnace mounted under the opposite end of the tunnel, andcommunicating therewith, a miX- ing chamber mounted above the rear endof the furnace below the tunnel, said chamber being provided with portswhich communicate with the furnace and with the tunnel, passageways onthe sides of the furnace, and mixing chamber, provided with ports whichcommunicate with the atmosphere and with the mixing chamber, whereby theproducts of combustion are mixed with air as they pass through themixing chamber, substantially as specified.

2. In a drier, a tunnel, a stack communi eating with one end thereof, afurnace mounted under the opposite end and com municating therewith, amixing chamber between the tunnel and the furnace, said mixing chamberbeing provided with two series of ports, one series of which provides acommunication between the furnace and the tunnel, and the other seriesof which provides a communication between the outside atmos phere andthe mixing chamber, the end of said tunnel opposite the stack beingprovided with air openings located above the furnace, whereby theproducts of combustion are mixed with air before entering the tunnel.

I11 testimony whereof we affix our signatures, 111 presence of twowltnesses.
